Abstract

New complex salts [Pd(NH3)4][Pd(NH3)3NO2][RhOx3]·H2O and Na3[RhOx3]·4H2O are prepared. The crystal structures of obtained compounds are determined by XRD. Complex salt [Pd(NH3)4] [Pd(NH3)3NO2][RhOx3]·H2O is studied by powder XRD, IR spectroscopy, and elemental analysis. The state of rhodium(III) in oxalate solutions is studied by NMR. Thermal behavior of [Pd(NH3)4][Pd(NH3)3NO2] [RhOx3]·H2O in various gas atmospheres shows that final thermolysis products in reducing and inert atmospheres are solid solutions Pd1–xRhx.
